וַיֹּ֤אמֶר אָחִ֙יהָ֙ וְאִמָּ֔הּ תֵּשֵׁ֨ב הַנַּעֲרָ֥ אִתָּ֛נוּ יָמִ֖ים א֣וֹ עָשׂ֑וֹר אַחַ֖ר תֵּלֵֽךְ׃
Le frère et la mère de Rébecca répondirent: "Que la jeune fille reste avec nous quelque temps, au moins une dizaine de jours, ensuite elle partira."
Mishnah Ketubot
A virgin is given twelve months from the [time her intended] husband claimed her, [in which] to prepare herself for marriage. Just as [such a period] is given to the woman, so is it given to the man to prepare himself. A widow is given thirty days. If the time has come and they were not married they are entitled to receive maintenance from the man’s estate and [if he is a priest] they may eat terumah. Rabbi Tarfon says: They give her [all of her food] in terumah. Rabbi Akiva says: One half unconsecrated food and one half terumah.
